Here's an example of what used to be an annual tradition: the appearance of adverts hawking the US Fall Saturday Morning schedules on the three US networks, published in US comic books.
For British readers, these were early indicators of what we *might* see on UK screens over the following few years. The BBC and ITV had strict limits on the amount of imported cartoons they could show so - if the shows crossed the Atlantic at all - it might be more than a year before they hit British screens.
At this time, the networks and Saturday mornings were still the main place to find kid-vid. Cable was starting to make inroads but their children's offering was often limited or restarted to off-network reruns. Weekday afternoons were generally given over to shows aimed at adults (soaps, audience shows and gameshows) although syndicators were starting to make inroads with off-network (and often toy-related) fare like HE-MAN AND THE MASTERS OF THE UNIVERSE, THE TRANSFORMERS, G.I. JOE and numerous wannabes.
Someone slap me if I'm wrong but I don't think any of the traditional broadcast networks offer a kids schedule on Saturdays anymore. 24-7 (or thereabouts) cable has made it a redundant (and far less commercially viable) proposition.
This particular ad is from Marvel comics dated December 1984. Thanks to the three-months-ahead cover dates used on comics at the time, this would have gone on sale September/ October time... just in time for the start of the new season. By the time sea freight copies reached British newsagents it probably WAS December!
NBC was the top-rated network in both primetime and Saturday morning at this point (thanks to the runaway success of - of all things - THE SMURFS) so the big spending network splashed out for the centre pages of Marvel's December editions. This originally appeared as a double-page spread but my scanner isn't large enough so I've chopped it into two single pages.
